Hello Alan, check this other thread I started:
viewtopic.php?f=32&t=8663&e=0I don't think the problem is in the DHT22, I'm having the problem with nothing connected.
Tried 160,330 and 660R. Better but doesn't solve.

It's now 2017 and so this problem has been around for 2+ years.
I can replicate the problem as stated... deepsleep runs normally on an Adafruit Huzzuh for a while (minutes, hoyrs, days) and then for some reason, when it comes out of deep-sleep, it enters a mode that "looks" like it's in upload mode (because the LED is half on) but it neither accepts an upload, NOR will it run again just by pressing reset.
I initially thought this was a case of a bard board, because when I replaced the Huzzuh, it stopped failing, but several weeks later it's now doing it again.
It's almost as if the Deep-Sleep function is effected by the age of overall runtime of the ESP8266 module.
ie: the more times it's run, the more likely it is to fail next time. Perhaps a FLASH wearing out issue that makes deep-sleep wake up oddly.
Extremely frustrating, and the probably reason why no-one has released a reliable low power product based on the ESP8266
More info: Normally my code starts up as follows (if I set the monitor baud to 74880)
etc Jan 8 201#,rst Cause:2, boot mode:(3,6)
load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
Csum 0x2d
v09f0C112
~ld
But once the failure occurs, each time I press reset, I only get:
etc Jan 8 201#,rst Cause:2, boot mode:(3,6)
etc Jan 8 201#,rst Cause:2, boot mode:(3,6)
This is NOT my code..... It's in the firmware.
